Product Description


GU-10 Universal Acrylic Primer is a reinforced product for general applications, to prepare a good base for plasters, screeds, fillers, glues, paints, tiles etc., intended for general indoor and outdoor applications. The primer improves adhesion and regulates exchange of water vapour.

Composition: water-based acrylic dispersion, preservatives and additives improving the properties and the application.



The surface should be dry and stable, all loose layers or old painting coats should be removed to obtain a uniform structure. Surfaces with fungi and mildew should be mechanically cleaned and then disinfected with fungicidal impregnant. 

Can be applied on: absorptive substrates and backgrounds of reduced adhesion such plasterboards, calcium-silicate bricks, cement plaster, cement-lime plaster, gypsum plaster etc.

Do not apply on: degraded substrates (deep-penetrating emulsion recommended), non-absorbent surfaces such terrazzo, OSB, varnishes (super primer with quartz sand needed).


The primer is ready to use after shaking the container. The product can be applied manually (with a brush or roller) or by airless sprayer to the substrate which is above +5°C. Absorptive backgrounds and backgrounds of reduced adhesion should be primed twice. Before applying the plaster, putty, adhesive or paint allow the primer to dry / harden well.

Drying time on absorbent substrates is between 2-24 hours, depending on the absorption of the ground, air and substrate temperature or humidity. When working in enclosed areas, ensure that there is adequate ventilation.

When dried, it forms a high-adhesion protective film resistant to scratches and strikes, regulating exchange of water vapour and improving covering power.
